-Subject: [PATCH 509/513] net-next: mediatek: add support for mt7621
-
-Add support for SoCs from the mt7620 family. This include mt7620 and mt7621.
-These all have one dedicated external gbit port and a builtin 5 port 100mbit
-switch. Additionally one of the 5 switch ports can be changed to become an
-additional gbit port that we can attach a phy to. This patch includes
-rudimentary code to power up the switch. There are a lot of magic values
-that get written to the switch and the internal phys. These values come
-straight from the SDK driver.
